Abstract

SUMMARY

Host cell reactivation (hcr) of phage T1 by two strains of 12, Hfr ( ) and Hfr 1 ( ) , was studied. Strain Hfr showed decreased ability to reactivate ultraviolet (u.v.)-irradiated phage T1, as predicted from its behaviour in mating experiments after thymine starvation. Thymine starvation of host Hfr 1 bacteria resembled u.v. irradiation in decreasing hcr, but thymine starvation of Hfr increased hcr, apparently as a result of induction. The presence of prophage in 12 was found to decrease hcr.
